HAND PUMPS HYDRAULIC COMPONENTS

Product catalog summary

Overview: This document provides comprehensive technical specifications and diagrams for various hydraulic components manufactured by HV Hydraulic S.r.l., including hand pumps, foot pumps, levers, oil tanks, flow dividers, and flow inverters. These components are designed for hydraulic applications, particularly for single-acting and double-acting cylinders, and include features such as pressure relief valves and dual pilot check valves.

Specifications:

Materials: Components are made from cast iron, white zinc-plated steel, and stainless steel AISI 316, with Niploy-treated pistons for enhanced durability.
Pressure Relief: Standard pressure relief valve settings are at 100 bar, with some models reaching up to 350 bar.
Sealing: A triple sealing system is employed to prevent oil leakage.
Mounting Options: Pumps are designed for wall or tank mounting.

Product Variants:

PMP 20, PMO 50, PMO 70 Series: Hand pumps with varying displacement capacities (20 to 70 cm³) and features like release hand knobs and pressure relief valves.
PMD and PMDVB Series: Double-acting hand pumps with flow dividers and dual pilot check valves.
Foot Pumps: Designed for single-acting cylinders with a 1.5-liter tank and a pressure relief valve set at 200 bar.

Effort Diagrams: The document includes effort diagrams illustrating the relationship between pressure and effort required by the lever for optimal operation, aiding in understanding the efficiency and ease of use of the pumps.

Key Parameters:

Displacement: Ranges from 6 to 70 cm³ depending on the model.
Pressure: Maximum pressures reach up to 350 BAR for certain models.
Mass: Varies by model, with specific codes for versions with and without bellows.

Additional Components:

Levers: Available in different lengths and weights, compatible with various pump models.
Oil Tanks: Steel and aluminium tanks with capacities ranging from 1 to 20 liters, featuring suction pipes and breather caps.
Flow Dividers and Inverters: Available in various configurations and sizes, designed to handle specific flow rates and pressures.

Conclusion: The document serves as a comprehensive guide for selecting and understanding the technical aspects of hydraulic components offered by HV Hydraulic S.r.l., providing essential information on specifications, operational parameters, and installation options.
